CARVlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 602,887, dated April26, 1898.

Application filed Augu t 28,1894. Serial No. 521,550. (lilo model.)Patented in France August 17, 1894, 1101403073 in Germany September 23,1894,1To. 82,220, and in Austria October 23, 1895, No. 45/3,?392.

To all whom it may concern.-

Be it known that I, ARNOLD WAOHE, of 24 None Tauentzienstrasse, Breslau,in the Kin gdom of Prussia, German Empire, have invented new and usefulImprovements in Carving- Machines, (for which I have received a patentin Germany, No. 82,220, bearing date Sep tember 23, 1894; in France, No.240,807, bearing date August 17, 1894, and in Austria, No. 45/3,992,bearing date October 23, 1895,) of which the following is aspecification. I

My present invention relates to a carvingmachine for copying plasticalarticles. The new machine difiers from the constructions hitherto knownin that the middle frame carrying the tool-holders and the feeler is notslidable in a longitudinal direction and that the same is jointed to thetool-holders, while in the copying-machines hitherto in use the wholemiddle frame and the gear-shaft connected with it must he slid in alongitudinal direction. The execution of the present machine is greatlysimplified by this modification and its handling is rendered a greatdeal easier, as the middle frame is only to be arranged rotatorilyin itsbearings and the possibility of a longitudinal sliding is not providedfor. Besides, the jointed connection of the tool-holder with the middleframe permits the copying of one model to the right and left.

This new machine is illustrated by the accompanying drawings, namely:

Figure 1 is a front view of the machine. Fig. 2 is a plan of the same.Fig. 3 is a section. Fig. 4: is a lateral view; and Figs. 5, 6, and 7represent the principal constituent of the machine, consisting in thedetails of a movable tool-holder.

The whole machine consists of the following two main parts: first, theframe, and, second, the tools, with the parts transferring the movementof the driving-shaft on the same.

The frame consists of two lateral frames a, fixed to a table I). Thetable-plate 6 serves to hold the pattern and the materials to be worked.Each of the side frames a is provided with a rail 0. The tool-holders dare arranged in a frame 6 and in such a way movably connected by theconnecting-rods f with the middle frame g as to be turnable out of theircentral position to the right or left. In Fig. 2 these alterations ofposition are indicated by dotted lines.- The middle frame g (see Fig. 6)carries the vertical driving-shafts g'in a quantity corresponding withthe number of the tool-holders. These vertical shafts carry the pulleysg for the tools. The whole frame 9 is turnably arranged inverticallyadjustable bearings g by means of two long pivots g".

The shaft i, which carries the pulleys t" for the vertical shafts g andwhich is itself driven by means of the shaft is of the gearing m, isfirmly connected with the frame 9 by some bearing-arms h. The connectionbetween the shafts 7c and c' is movable, so that the tools can be keptin motion withevery position of the frame 0. The bearings 9 which carrythe middle frame 9, are vertically adjustable in guides at and suspendedto chains 0 of the counterweight o',which serves to balance thetool-holders, with their frames, and the parts transmitting themovement; but besides this the Whole supporting-frame for the middleframe g, which principally consists of the guides '12, and theconnecting-support p, can, by means of the rollers r, be horizontallymoved on the rails c. The frame 9 being thus vertically and horizontallyadjustable and being able to swing round its horizontal turning-pivots git is clear also with regard to the movable connection between themiddle frame 9 and the front frame a that the tool-holders can be givenany position required.

In constructing the whole apparatus I have attached special importanceto the circumstance that the dimensions of the tool-holders themselvesand of the parts transmitting the movement and effecting the connectionfor every tool-holder should be exactly the same, so that the movementsand alterations of position of all tool-holders must turn out exactlyalike.

The tool-holder consists of an outside casing s and a rotatory innerpart cl. The interior body carries the shaft (P, at the lower end ofwhich the working tool is arranged.

It is obvious that in turning the inner part 01 in the frame 3 the shaftd and with it the tool, is compelled to follow the rotation of part d,so that a slanting position is gained. If one has to copy a model inwhich underworked places are to be found, the slanting adjustment of alltools is a necessity. In order to attain the uniform adjustment of alltools, the outer frame 3 is provided with a scale, while theinnerslidable part d is provided with a pointer d, by means of whicheach tool may be adjusted in an equal angle.

The machine WOIkS in such a way that under the central tool-holder thepattern is placed, while under every other tool-holder a piece of rawmaterial of a size corresponding with the pattern is fixed to thetableplate, whereupon the worker leads the point of the one tool overthe contours of the pattern, the other tools being forced to executeexactly the same movements on the material lying underneath them, thusdelivering exact copies of the original to be copied.

Having now described my invention, what I claim, and desire to secure byLetters Patcut, is

In a machine for copying plastic articles, the combination of a middleframe adjustable in vertical and horizontal direction and adapted toswing around its horizontal axis, with a frame pivotally connected tothe middle frame, and tool-holders pivotally arranged in the said frame,substantially as and for the purpose set forth.

In witness whereof I have hereunto signed my name in the presence of twosubscribing witnesses.

ARNOLD WAOHE.
